Risk of serious harm from vaccines from a country where I trust the people a lot more than Americans is 1:3571 (based on 446,380 doses). Where are you getting the 1:200,000 from?

That point being addressed, I would expect the elderly to have a lot more background adverse events, such as death. If we live 28835 days on average, 15 people in this vaccinated group are expected to die every day from non-vaccine causes, and heavily weighted towards the elderly. But I'm not even seeing death as a side-effect, and the number of adverse events among the elderly (who got the vaccine first and have had the lions share of vaccine administration) is actually less than among younger groups. This perplexes me and if anyone thinks they know the answer to this riddle, please share.
[Oh wait... there aren't as many elderly people. hits head]
But here too the reporting is open to anyone, and is voluntary. So chances of large under reporting is present here as well. Which is a bit scary..
